here it is http://www.specpointbatteries.com/ . lots of people on the traxxas forums for the e-maxx have these and they rave about the batteries he builds and he can put them in various configurations. and ythey are the cheapest in price for the ib 4200 7 cell packs. just charge them and follow his instructions on how to use the batteries and you wont have problems.
i had another question i wanted to go with a 9xl so i could use it in my e-maxx as well. is this a good motor for savage use? i will go higher in cells when i get my new charger but for now its going in my e-maxx with 14 cell ib 4200 from spc. thanks
